I made a comment earlier about how the different GI Joe staff is into different aspects of GI Joe. I think Blaylock even admitted coming in 'late' to the GI Joe universe. The example that was used was that Blaylock chose Lifeline over Doc because he was familiar with Lifeline but not Doc. If you guys read some of Justin's reviews, he gives a little bit of insight on what the sculptors really preference. There are, apparently, some DD fans there and the DD influence crept into the toyline. Zartan, Serpentor and even Firefly are prime examples.
